GEORGE KABURECK, OF JERSEY CITY, NEW JERSEY.

VEN'IILATOR.

To all whom it may concern:

Be it known that I, GEORGE KABUREoK, a citizen of the United States ofAmerica, and residing at Jersey City, in the county of Hudson and Stateof New Jersey, have invented certain new and useful Improvements in,

Ventilators, of which the following is a specification, such as willenable those skilled in the art to which it appertains to make and usethe same.

This invention relates to ,ventilators and particularly to windowventilation and is an improvement over that shown and described in myUnited States Patent No. 753,579, of March 1st, 1904, and the objecthereof is to provide means for ventilating rooms, halls, etc., throughthe frames of the openings in a building; a further object being toprovide a ventilating device which is ada ted to wood frames and whichmay be insta led in either new or old buildings without any materialchange in the original construction of the window frames thereof; afurther object being to provide a ventilating device for windows whichpermits the greatest possible light area in proportion to the area ofthe opening; a still further object being to provide means whereby sashweights may be placed in position, because of my invention, withoutweakening the frame and dispensing with the usual removable member ofthe sash run employed and a still further object being to provide apartition plate in the sash weight boxes which accommodates itself tovarious inequalities of the said weights or to imperfect hanging thereofwithout in any way interfering with the ventilating features of theframe.

My invention is fully described in the following specification, of whichthe accompanying drawings form a part, in which the separate partsdesignated by the same reference characters in each of the views, and inwhich Figure 1 is an external elevation of a window frame provided withmy invention, one side thereof being taken on the line 11 of Fig. 2;Fig. -2 is a section taken on the line 2"2 of Fig. 1; Fig. 3 is a viewsimilar to Fig. 2 but showing a modification of the construction; andFig. 4 is a section on the line 44 of Fig. 3.

In the drawings forming a part of this application, I have shown aportion wof a build ing, built of brick but which may be of wood orother material, and provided with a win- Specification of LettersPatent.

Application filed July 5, 1907.

Patented May 5, 1908.

Serial No. 382,154.

dow opening in which is placed a frame a comprising a top member of,side members a and a sill a and the side members a are divided into sashweight compartments o which I sub-divide by means of a partition plate ahung centrally of the compartment a as shown at a in order to permit offree pendulum movement thereof and provided with openings a for thepassage of air.

As in the patent referred to, I provide an opening I), at the bottom ofthe inner side of the frame (1 preferably covered by a perforated plate5 and, if desired, a closure device may also be provided therefor, asshown in the patent cited; adjacent to the top of the frame a andcommunicating with the compartments a, are external openings 0 into awhich are fitted casings a open at the front and rear to permit thepassage of air from the said compartments outwardly and the casings care provided with a plurality of in clined plates or louvers c to changethe direction of air and to prevent the inrush of wind, this being alsoprevented by means of a double curved bafiie or deflector plate 0arranged before the louvers 0 The casing c is provided with side flangesc and end flanges 0 to secure the said casing in position, the latterflanges being covered by the usual stafi bead or molding c and it willbe seen from this construction that free ventilation of a buildingprovided with my invention results without the danger of draft andwithout requiring special construction of the window frame and withoutmaterially weakening the same, at the same time permitting the insertionof sash weights through the openings 1) by the removal of the perforatedplates b this permitting the insertion of weights of greater dimensionsthan is possible where the opening for the insertion thereof is in thesash run, as is usual, and therefore maintaining the entire strength ofthe said sash run and a smooth sliding surface thereon.

In Figs. 3 and 4, is shown a modification, I

tom of the desired openings therein and bending the said flangesoutwardly at the jointure thereof with the said plate, this constructionbeing known as the fish scale form, and with the construction shown inFigs. 3 and 4, the deflector plate 0 may also be employed if desired.

In the operation of the invention, the air becoming heated and vitiatedin a room passes through the plate 5 thence upwardly through thecompartment a and outwardly through the louvers or fish scales andaround the deflector plate 0 to the outer air, the double curve of thisplate serving to deflect air currents from any possible direction andthereby preventing wind or draft in the rooms provided with my inventionand various kinds of deflector plates may be employed as may alsovarious kinds of the plates 0 or d in order to accomplish the resultdesired and, with this reservation,

What I claim as new and desire to secure by Letters Patent, is

1. A ventilating device, comprising a window frame, provided with theusual weight pockets, each of which is provided with inner and outeropenings, means for deflecting air adjacent to said outer openings and aperforated partition plate loosely swung in each of said weight pockets.

2. A ventilating device comprising a window frame provided with theusual weight pockets, each of which is provided with inner and outeropenings, plates adjacent said last named openings and arranged at anangle to the direction of the air therethrough, and a partition platesuspended in each of said weight pockets and capable of movement in .alldirections.

In testimony that I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 2nd day of July 1907.

GEORGE KABURECK.
